DOY PUNTOS AL QUE ME RESUELVA ESTO: Se tiene 28 cm3 de una solución de Cloruro de Potasio, que contiene 3 g de KCl. La
solución tiene una densidad de 1,05 g/cm 3 .Calcular:
a) %m/ v b) % m/m c) Molalidad d) Xsv

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

B.) falsehope this !

A1 a 2 a 3 ooh lol i think that's it
